Last year for our STEM Fair we created a few interactive stations with the Circuit Playground using MakeCode. The idea was that anyone could walk up, make minor changes to the code, and then see how it changed (light colors, sounds, speeds/durations, etc). This was really cool but the tricky part was resetting code back to a starting point and sort of keeping things tidy within the guardrails.

I wonder if anyone else has experience making things like this, and if [Code.org/App](http://Code.org/App) Lab has any features I may be missing that would support it.

First off, welcome to the forum! I wish I had something to add to your idea. I really love it! I’d love to hear how people interact with this station!
